Application filed June 9, 1905. Serial No. 264,514.

.To all whom, it may concern:

Be it known that I, MAcnANUs B. PEERY, a citizen of the United States,residing at Rogers, in the county of Benton and State of Arkansas, haveinvented a new and useful Coffee-Pot, of which the following is aspecification.

My invention relates to coffee-pots, and especially to that class ofcoffee-pots wherein the ground coHiee-berries are held in a fabricreceptacle or filter.

Itis well known that in coffee-pots wherein the filter fabric is heldmechanically by clamping means great difficulty is experienced insecuring the fabric so that the weight of the not disengage the filterand precipitate the coffee-grounds into the infusion.

It is an object of my invention to provide a device of the classdescribed wherein the filter cloth or fabric may be quickly and securelyclamped in position so as to effectually prevent accidental displacementof the same.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claim, it being understood thatl changes inthe form, proportion, size, and minor details may be made within thescope of the claim without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is a longitudinal sectional view of acoffee-pot constructed in accordance with my invention. Fig. 2 is aperspective view of the filter-tube detached. Fig. 3 is a similar viewof the binding-ring. Fig. 4 is a longitudinal sectional view of aportion of the pot, showing the manner of clamping the filter-cloth inposition.

Like characters of reference designate corresponding parts throughoutthe several views.

ln its preferred embodiment my improved coffee-.pot comprises areceptacle 1, having the usual handle 2 and provided with a perforatedflange 3 at the bottom thereof. Within tl'fe upper end of the receptacleis disposed the filter-tube 4, the latter being tapered toward the loweropen end and provided with an outturned flange 5- at its upper open end.The filter-tube is proportioned for insertion within the upper openingof the receptacle 1 and With the flange 5 resting upon'the upper edge 6of said receptacle. Within the filtertube 4 is disposed thefilter-binding ring 7, having an angularly-disposed biting-flange 8outturned from its upper open end. The binding-ring 7 may be providedadjacent its lower end with perforations 9, which when the ring isplaced within the receptacle extend below the tube 4. A fabric filtermaterial 1() is disposed over the lower open end of the binding-ring andextends upwardly between the binding-ring and the tube, being firmlygripped between the biting-flange S and the tapered sides of the tube 4,as shown. Acover 11 is provided having a tapered flange 12, proportionedto be inserted within the filter-tube 4 and to contact with the flange Sof the binding-ring, so as to force the ring Within the tube and expandit. The receptacle 1 is provided with a discharge-spout 13, having itsupper extremity 14 extended above the level of the edge 6 of thereceptacle.

The operation of my improved coffee-pot isv as follows: The fabric orfilter cloth 1() is placed over the lower or reduced open end of thebinding ring 7 and drawn upwardly around the ring externally to andabove the biting-ange 8. The ring and fabric are then inserted Withinthe filter-tube 4 and pressed downwardly until the biting-flange clampsthe fabric firmly between the fiange and tle tube. The filter-tubecontaining the filter and binding-ring are then inserted within the topof the receptacle 1 with the apertures 9 extending below the edge of thetube 4 and covered by the fabric 10. Ground coffee may be placed withinthe ring 7 and upon the fabric 10 and water poured thereover in anydesired quantity. The cover 11 being inserted within the filter-tube 4will contact with the fiange 8 of the ring 7 and expand the ring7against the tube 4 to more firmly clamp the fabric 10.

From the foregoing it will be obvious that the greater the pressureexerted by the material Within the filter the more firmly will thebiting-fiange grip the fabric against the tube, and thereby preventaccidental displacement of the fabric or filter cloth.

Should the binding-ring be carelessly or iiegligently placed within thetube 4, thus iiisecurely binding the filter, the iinplacemeiit of thecover 11 upon the pot will overcome any trouble which might result byforcing the binding-ring firmly to its seat.

It will be noted that the end 14 of tle spout 18 extends above the levelof the edge 6 of IOO IIO

the receptacle l7 thus lessening the danger of the liquid being forcedout of .the spout by the expansion of air or steam under the filter orfrom pouring too much Water into the ilter.

Having thus described the invention, what is claimed is- A potcomprising a receptacle provided with a discharge-spout, a tapered tubeproportioned to be inserted in the upper open end of the receptacle andhaving a flange at its larger end to engage the upper edge of thereceptacle, a tapered ring proportioned to slide Within the tube andprovided at its larger end Wthan outturned obliquely-disposed flangehaving its outer periphery formed into a biting edge, and a cover havinga flange proportioned to be placed Within the tube and adapted to engageand expand the ring.

In testimony that I claim the foregoing as my oWn I have hereto affixedmy signature in the presence of two Witnesses.
